2 x Comb Filter Comb filters are short delay lines with a feedback path. They can be used for flanging effects or spectral mangling of sound. The feedback can cause self oscillation. When played “in tune” with some damping, comb filters provide a vast source of “alive” sounds. This is often used as a building block for digital models of natural instruments such as strings and wind instruments.

* 5 modes with different types of feedback networks
* up to 4 comb filters in the network
* PreFill function initializes delay buffers with noise
* frequency independent feedback
* damping and waveshaping of feedback signal
* control of delay time ratios
* alternative input point for some types (Flavour)
